I have the internet connection set up and tested, all is ok. I cannot see it on my computer network nor any music or pics on my menu of the HR20. I tried all of the helpful hints in this forum with no luck. In WMP11 file sharing no devices are listed.

Not sure why that happens. I have 2 computers that see the HR20 as an unidentified device. Another computer will not see it. I have tried maching all the security settings the same to no avail. The problem, I believe is not with the HR20 since yours test out ok on connection. All my computers using WMP11 and XP.

Can you see the HR20 as a DHCP client on your router?
Have you disabled any firewalls that may be blocking access?
Have you compared the IP settings on the HR20 to those on the rest of the network to be sure that subnet mask, DNS, and default gateway are the same, and the IP's are in the same range?

Yes to all of the above. I have checked all area's, the HR20 internet connection tests good and still can't see it on the network.

I just finally set up Media Sharing today and had one computer that had trouble seeing the HR20. My daughter (who knows more about computers than I do!) and I had to change the firewall settings in a couple of ways to get it to be seen: 1) clicked "allow" on more than just WMP, and 2) lowered the security setting to medium. Perhaps that will work.

hasan & cajunrc,
The HR20 does not respond to ping requests, so you can ping it all day the results will be the same.

Simplify and solve.

You may want to try bypassing the Buffalo adapter using an ethernet cable. Either get one that's long enough to reach across the floor or temporarily move the HR20 nearer to the router, hardwire it with a cable, and power it up to check it that way.
Obviously, if it connects that way, then the Buffalo has a problem in its configuration.

If you haven't tried thei configuration utility, you may want to give it a shot instead of the web-based interface. Alos make sure your firmware is the latest.

Reviewing the manual for the Buffalo adapter, there appears to be an option to assign the adapter's MAC address so that it mimics the MAC of the device connected to the first ehternet port.That could also be tried, but I'd do it after re-checking everything else, including running a temp cable to confirm that the HR20 can connect via hard-wire, and re-checking all firewall settings.

Here's something that worked for me when I had the same problem.

Go to "Start" click on "Control Panel" then click on "Administrative Tools" then click on "Services" go down to "SSDP Dicovery Services" and double click. Make sure you are looking under the "General" tab. Now go down to "Startup type" and select "Automatic" from the drop down box, then click "OK".

Now find "Universal Plug and Play Device Host", further down on the "Services" list, and double click on it. Make sure you are in the "General" tab again, and go down to "Startup type" and select "Automatic" from the drop down box, then click "OK".

Now you can close the "Services" window and the "Control Panel" window. Now open up "WMP11", go to the top and select the "Tools" tab then click on "Options" then click on the "Library" tab then click on "Configure Sharing....", then enable sharing. Hopefully you will get the "Unknown Device" which should be your HR20 and all should work.

This worked for me, but to clarify mine was showing Internet and Network connected before I did this. I figured this out from looking at the error messages in the "Event Viewer" which is also accessed from the "Control Panel" then "Administrative Tools" then "Event Viewer" then the "System" which brought up messages including error messages. Just double click on an error message to see what's going on when you are trying "Configure Sharing".

If you haven't tried to configure sharing in WMP11 do that before you try what I did above.

Hope this helps,Tim

FYI, I am running a Gateway with Windows XP Media Center Edition with WMP11. Am hardwired from HR20 to a Netgear WGR614 v5 Wireless router. My computer is hardwired into the router as well.__________________
